[Linux-cluster] Kernel messages causing node to be fenced out - Bug?

We have a setup with two HP DL360 nodes connected to an MSA500 disk array via SCSI cables. We are running RH4U3 and our product has an active passive design. The Active-passive is managed internally in the product.

Every now and then one of the nodes outputs the below kernel messages after which the other node fences it out. This causes a failover for our product.
